BT-16B Wireless Transmitter Operating Instruction Audio signal is input through MIC.After preamplified and noise compressed,the signal will mix with carrier signal controlled by PLL circuit (16 selectable frequencies) to form modulation signal.The modulation signal will be transmitted to sky after RF amplification circuit and antenna radiation. The sample power is supplied by DC 3V(2*AA battery) and the modulation type is FM, antenna type is internal. PDF 文件使用 "pdfFactory Pro" 试用版本创建 www.fineprint.com.cn
